Description
Summary:<i>Colletotrichum graminicola</i> can cause leaf spots and stalk rot in maize. The primary function of carbohydrate esterases (CEs) is to eliminate ester modifications from monosaccharides, oligosaccharides, and polysaccharides, thereby facilitating the hydrolysis of sugars. We identified 128 <i>CE</i> genes through whole-genome analysis and functional annotation of <i>C. graminicola</i> TZ–3 here. We further analyzed the physicochemical properties, subcellular localization, conserved motifs, gene structures, promoter regulatory elements of these 128 <i>C. graminicola CE</i> (<i>CgCE</i>) genes. Our results indicated that half of the <i>CgCE</i> proteins were located extracellularly. The <i>CgCE</i> proteins demonstrated diversity in both their structures and motifs. Furthermore, the <i>CgCE</i> gene family contained numerous conserved domains, suggesting potential functional diversity. Regulatory elements associated with various stresses and plant hormones were identified in this study. GO enrichment and expression pattern analysis indicated that the <i>CgCE</i> genes were involved in metabolic processes and might contribute to the establishment of fungal infections and lesion expansion. These results enhance our understanding of the <i>CE</i> family genes in <i>C. graminicola</i> and provide a foundation for further investigations into their roles in fungal pathogenesis.
